Q. Formation of alkane by the action of zinc on alkyl halide is called
A) Wurtz reaction
B) Kolbe’s reaction
C) Ulmann’s reaction
D) Frankland reaction
Explanation
(d)
(i) Wurtz reaction
$2RX + 2Na\overset{Ether\ \ \ }{\rightarrow}R - R$
Alkane
(ii) Kolbe’s reaction
$RCOONa + H_{2}O\overset{Electrolysis}{\rightarrow}R - R$
alkane
(iii) Ulmann’s reaction
$2C_{6}H_{5}I + 2Cu \rightarrow C_{6}H_{5} - C_{6}H_{5}$
biphenyl
(iv) Frankland reaction
$2RX + Zn \rightarrow R - R$
alkyl halide alkane
